with ver}- small vein-dots, fourth and fii'rli lines geminate, not very distinct, 

 aceentnated by vein-dots, dots of fifth line heaviest on M^ and SM-, spot M* 

 corresponding to the upper part of the oblique double spot of ptmllus, no subapical 

 costal spot ; distal margin evenly dentate, teeth R' and M' not more prominent 

 than the others ; a brownish marginal area as in pusillus, but this area of about 

 the same width between SC^' and R^,' not being obviously narrowed costad, the 

 brown submarginal halfmoon SO'— SC^ of pKsillus not marked in the present 



species. Hindwing more elongate than in pusillus, aual angle less i)rojecting ; 



clayish creamy buff, a pair of discal lines filled in with rnsset-brown, the first 

 close to cell, even, tlie second dentate ; a third line about halfway between first 

 and distal margin, convex from to M^ then almost straight, slightly dentate 

 on W and M- (the teeth pointing basad), the line most distant from outer 

 margin at W ; distal area, outside the pale distal border of tlie third line, russet- 

 brown, witii small deeper brown spots on M', M-, SMI 



riuh'rside grey, shaded with pinkish russet, costal margin of forewing, basal 

 area and second discal interspace of hindwing pinkish grey, basal area of forewing 

 isabella-colour ; both wings with four lines across disc, second very faint, the 

 others quite distinct also on forewing, parallel, the first on forewing 4 mm. from 

 cell at R'-, on hindwing at lower angle of cell. Harpe broad, short, the obtuse 

 apical portion produced dorsad into a very large tooth. Penis- sheatli armed at 

 end with a heavy, somewhat compressed, process, which projects sinistro-laterad 

 and is ol)li([nely rounded at apex, but ends in a minute point. 



? and early stages not known. 



Lengtii of forewing : 23 mm.

? . Upperside of head and thorax dark olive-brown, with a conspicuous pale 

 side-stripe ; mesothoracic tegula with a prominent pale yellowisli middle line ; a 

 ])ale, simple, mesial vitta from pronotum to end of abdomen, accompanied on the 

 latter by a blackisii brown line at each side : abdomen j)aler than thorax, except at 

 base, sj)eckh'd with dark olive dorso-laterally, no black basal side-patch. Underside 

 pinkish cream-colour, faintly speckled with olive ; second segment of palpus and 

 sides of breast dark olive. 



Wings, upperside. Forewing as in //. I'son, mucli more grey, less clayish ; 



discal lines 1 and 2 forming a band as in //. cson, but this band continued to the 

 very base, being proximally almost black ; line 0, which is as prominent from R* to 

 apex as in esoif, is very thin between R- and hinder margin, and accentuated by dots 



on the veins. Hindwing nearly as in H. osi)-is, purplish red, deeper coloured than 



in osi7is ; the black discal area larger, its posterior portion not separated from the 

 anterior portion, the red band-like space traversed by black vein-streaks ; the post- 

 discal black band less sharply defined than in osifis, tapering behind ; tlie jiale 

 distal marginal border sjieckled with black. 



Underside almost exactly as in //. celerio ; no red colour and'no distinct lines ; 

 brown distal marginal band of forewing more distinct than in //. osiris, and 

 obviously broader than in //. eson. 



Length of forewing : 38 mm.
